Survival Mode
In the early versions of Minecraft Classic, specifically from 0.24 to 0.27, there was a test version of survival mode. Although subsequent Classic releases were focused exclusively on creative mode, the internal code for survival still remained in the game.
The Survival Mode modification activates this hidden functionality in version 0.30, using the game's remaining mechanisms. This mod is specifically compiled for the obfuscated version 0.30 and will not work with other creative releases issued after 0.27.
To run Survival Mode, you need to install Fabric Loader along with Classic. There is currently no automatic installer available, so you'll have to manually configure the launcher's JSON files.
